An NGO-ran tour was suggested to us by Addie's aunt Wyler, who had just come from Siem Reap when we met up for our time in Hanoi and Ha Long Bay a few days before. KKO (Khmer for Khmer Organization) provides free english and vocational education to Khmer children in need. They fund their educational programs through a variety of projects, including the donation-based Off Track Tours, through which we booked a half-day motorcycle adventure around the Siem Reap countryside. Our guide took us to markets, farms, a monastery and other awesome sights via gorgeous country roads. He also shared information on the history of the area and its people, illuminating our experience in Cambodia substantially. We definitely recommend taking advantage of this organization's offerings to anyone traveling in the area.
